Descrição: We study the complete time evolution of scalar fields propagating in spacetimes of higher-dimensional Lifshitz black holes with the dynamical critical exponent z = 2, obtained from a theory including the most general quadratic curvature corrections to Einstein-Hilbert gravity in D dimensions. We also computed the quasinormal spectrum after performing a numerical integration and solving exactly the Klein-Gordon equation obeyed by the massive scalar field. We found that quasinormal modes are purely imaginary for all dimensions. Concerning the AdS/CFT correspondence, the results indicate that at higher temperatures, initial fluctuations of the thermal state defined at the boundary are not long-lived.
